[127.02] Preliminary results from an ISOCAM based search for brown-dwarfs in the Hyades

We report on a brown-dwarf survey at mid-infrared wavelength
in the Hyades open cluster. We used ISOCAM and either the
LW1 (4.5um) or the LW2 (6.75um) filter to image 24 fields
near proper-motion identified, low luminosity Hyads with no
known companions. We estimate a median 5-sigma flux
sensitivity of about 75 micro-Jansky for the 24 fields.

We identified four targets in ISOCAM images with no visible
counterparts on the Palomar Observatory Sky Survey (POSS)
plates. These targets were subsequently observed at
near-infrared wavelengths from UKIRT to confirm/reject
ISOCAM detections and to provide near- and near-mid IR
colours of the targets. In this contribution we present our
results and discuss the nature of these objects.
